I was going to blog about something else today, but I made the most delicious filet of beef for my family for our Christmas dinner a few days ago, and I had to share it with you. I was so impressed with the results and so were my family!  You will be too.

When I had Flavors Catering and Carry out on 18th St, this party filet was a dish that was requested so often. It’s in my cookbook, Pamela Morgan’s Flavors, and it makes the perfect entree for a dinner for 12. It’s tender and juicy and I serve it medium rare. The ends are more well done; so everyone can have their meat cooked the way they like it.

I created a sauce from a homemade apple butter that my son’s mother-in-law gave me and I mixed it with honey mustard and fresh rosemary. It was the perfect compliment to the beef. If you haven’t been given a homemade apple butter, you can use a store-bought apple butter.

The secret to the filet is the marinade. I don’t find that it has much flavor on its own, so this marinade really kicks up the flavor quotient. It’s a mix of soy, garlic, green peppercorns, mustard and rosemary. I like to let it marinate for 2 days. Then I sear the meat in a very hot smoking pan and finish it in the oven until perfectly medium rare or about 125 degrees. Make sure you let it rest before slicing. I served it with garlic mashed potatoes and fresh asparagus.

Christmas cooking fairy! I also served a delicious fish!

Enjoy, and Happy New Year’s to you and yours!
